WhatsApp has officially launched Incognito Chat for its AI services, delivering on its promise of totally private AI conversations that neither the user nor Meta can access. According to WIRED, WhatsApp head Will Cathcart explains that "people wanted to have private conversations with AI on sensitive subjects including health, relationships and finances and didn't want them to be accessible." The company announced the rollout as it looks to address growing data privacy concerns around AI assistant usage. Meta claims messages sent during an Incognito Chat are processed inside a secure environment that even Meta itself cannot access, with Cathcart noting that "We've heard from a lot of people that they feel some discomfort about sharing [personal] information with the company, yet they want the answers."
As reported by Business Standard, Meta says starting an Incognito Chat creates a temporary AI conversation that is visible only to the user. The chats are not saved, and messages disappear by default after the session ends. The technology behind WhatsApp's incognito mode is "the equivalent" to the end-to-end encryption the platform uses to protect other messages, according to Cathcart. Unlike some existing incognito or private modes offered by other AI services, Meta's system is designed so that neither incoming questions nor outgoing responses can be accessed by the company itself. According to WIRED, Meta CEO Mark Zuckerberg confirmed that "Incognito Chat handles all AI inference in a Trusted Execution Environment that ensures your messages are not accessible to us." The feature includes a web search option that can be turned on or off by default, allowing the AI model to search the web anonymously for up-to-date information.
Cyber security expert Prof Alan Woodward from Surrey University told the BBC that there is low risk of compromising WhatsApp's existing security by introducing a second system, but raised concerns about accountability. Woodward expressed concern about how incognito mode could hide AI malfunction or abuse, noting there is risk of a lack of accountability for the AI's responses. He warned that "disappearing messages which cannot be retrieved by the user or by Meta would mean it would be impossible to find evidence whether somebody's chats led to harm, death or suicide." Woodward emphasized that "Personally I think what you ask an AI should remain private as some people ask it very personal matters - but you are placing a great deal of trust in the AI not to lead users astray."
According to Business Standard, Meta says Incognito Chat will begin rolling out gradually on WhatsApp and the Meta AI app over the next few months. The company has not yet shared a specific global availability timeline or device compatibility details. The announcement comes at a time when AI chatbots are increasingly being used for personal queries, including health concerns, financial advice, workplace discussions, and other sensitive topics. With more than 3 billion users around the world, as reported by WIRED, Incognito Chat may offer many people their first opportunity to interact with an AI chatbot. The feature is currently text-only but support for image processing and voice recognition is in development, with the company working to reduce latency by optimizing routing within the secure cloud environment. As reported by TechCrunch, users can start an incognito session by tapping on a new icon in one-on-one chats with Meta AI, and the feature will also be available on the standalone Meta AI app.
According to Wealth Club's Susannah Streeter, Meta is on track to shell out $145bn on AI infrastructure in 2026, with investors wanting to see significant returns on this massive investment. Streeter noted that "Investors are nervous about the scale of the spending, but Meta is counting on the push leading to significant returns." She explained that Meta is building out AI infrastructure to supercharge its platforms, stating that "if it works it could make its advertising and commerce empire even more dominant." The launch of Incognito Chat represents a key component of Meta's AI strategy as it seeks to differentiate its platform through enhanced privacy features while addressing user concerns about data sharing with the company.
